A communications network comprises a lower transport layer and an upper overlay incorporating a plurality of routers. Adjacencies are defined between respective pairs of routers. Path protection is provided by defining a software model of the overlay of the network and defining in the model a hierarchy of protection levels for the main path. Each protection level is characterised by a respective s...

A dispenser body supports a nozzle cap for rotation about a longitudinal ax is thereof between ON and OFF positions. A nozzle cover surrounds the nozzle ca p, is freely rotatable about the nozzle cap and is movable along the longitudinal axis relative to the nozzle cap, to render the same child resistant. Engaging portion on t he nozzle cap and the nozzle cover are longitudinally spaced apart in a...

A Near Optimal Fairness (NOF) algorithm is disclosed for resolving data collisions in a network shared by a plurality of users. The NOF algorithm calculates an optimal back-off or contention window which is broadcast to users competing for system bandwidth. The NOF algorithm handles data contention in cycles and guarantees that each user competing for system bandwidth within a cycle will make a s...

A circuit and method for controlling a battery (12) are provided. The circuit (18) includes a switching device (24) disposed between first and second poles (20, 22) of the battery (12) and responsive to a control signal. The circuit also includes a controller (26) that generates the control signal in accordance with a predetermined algorithm responsive to a temperature and a voltage drop across po...

Environment friendly hydrogen synergies comprising three complementary technologies operating in symbiosis, an Electromagnetic Propeller, an Electrolyser and a Hydrogen Rotary Generator, which are interfaced by water to the sun's energy to provide electricity, hydrogen fuel and propulsion, at once day and night - on demand. The basic concept provides an immensely diverse scope of potential applic...

This invention is a method and system to control engine shutdown in a hybrid electric vehicle (HEV). The invention allows for reduced tailpipe emissions during the many engine shutdowns and subsequent restarts during the course of an HEV drive cycle and reduced evaporative emissions, during an HEV "soak" (inactive) period. The engine shutdown routine can ramp off fuel injectors, control engine tor...
